[0026] Next, the technical solutions in the embodiments of this application will be clearly and completely described with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of this application.

[0027] The embodiments of this application provide an air conditioner indoor unit to solve the problem of direct blowing of cold and hot air of the air conditioner. The following will be described with reference to the accompanying drawings.

[0028] In the embodiments of this application, as Figure 1 and Figure 2 shown, this air conditioner indoor unit includes a main body 1, a first air deflector 2 and a second air deflector 3. The main body 1 is provided with an air outlet 11. The first air deflector 2 and the second air deflector 3 are both rotatably connected to the main body 1 to open or close the air outlet 11; the first air deflector 2 is provided with a gentle breeze area and a closed area;

[0029] When the first air deflector 2 is opened to a first opening angle and the second air deflector 3 is opened to a second opening angle, the first air deflector 2 abuts against the second air deflector 3 and blocks a part of the area of the air outlet 11, and the gentle breeze area of the first air deflector blocks the remaining area of the air outlet, so that the air flow at the air outlet 11 flows out through the gentle breeze area.

[0030] It should be noted that the gentle wind area refers to a structure with functions such as disturbing the flow direction of the air flow and increasing the diffusion range of the air flow; the closed area refers to a structure that blocks the outflow of the air flow from the air outlet. By the first air deflector 2 abutting against the second air deflector 3 and blocking the air outlet 11, the air outlet direction of the air outlet 11 is changed so that it flows out through the gentle wind area. The gentle wind area can disturb the direct jet flow flowing out of the air outlet 11, generate gentle wind, have a natural wind feeling, and improve the user experience in the cooling and heating modes. At the same time, the first air deflector 2 and the second air deflector 3 can be respectively opened to different opening angles, having a larger air guiding range; and by setting the gentle wind area on one of them, it can meet the requirements for a larger air outlet volume and gentle wind effect in different modes of the air conditioner.

[0031] In some embodiments, as Figure 2 shown, the first air deflector 2 is located in front of the second air deflector 3; in other words, the first air deflector 2 and the second air deflector 3 are arranged in sequence along the width direction of the air outlet 11. The first air deflector 2 is arranged close to the front panel of the main body 1, and the second air deflector 3 is located on the side of the first air deflector 2 away from the front panel, so that the first air deflector 2 and the second air deflector 3 are arranged in sequence from front to back.

[0032] In some examples, when the first air deflector 2 is opened to the first opening angle and the second air deflector 3 is opened to the second opening angle, the windward side of the second air deflector 3 is spaced relatively from the gentle wind area provided on the first air deflector 2. It should be noted that the windward side refers to the side facing the internal air duct of the main body 1, and the side corresponding to the windward side is the leeward side. In this way, when the air flow flowing out of the internal air duct of the main body 1 passes through the windward side of the second air deflector 3, it can be reflected from the windward side of the second air deflector 3 to the gentle wind area, and then better improve the gentle wind effect through the gentle wind area.

[0033] In some embodiments, as Figure 2 shown, the gentle wind area is provided with a gentle wind structure 4. The gentle wind structure 4 includes a gentle wind plate 41. The first air deflector 2 is provided with a ventilation hole 21. The gentle wind plate 41 is arranged on one side of the first air deflector 2 and covers the ventilation hole 21. The gentle wind plate 41 is provided with gentle wind holes 411, and the ventilation hole 21 and the gentle wind holes 411 are communicated. It should be noted that covering the ventilation hole 21 means that the air flow flowing out of the ventilation hole 21 can all flow to the gentle wind plate 41. In this way, the air flow is disturbed through the ventilation hole 21 and the gentle wind holes 411 to achieve a better gentle wind effect.

[0034] In some embodiments, as Figure 2As shown, the gentle wind panel 41 is located on the side of the first air guide plate 2 away from the second air guide plate 3. When the first air guide plate 2 is opened to the first opening angle and the second air guide plate 3 is opened to the second opening angle, the gentle wind panel 41 and the first air guide plate 2 are respectively spaced from the side wall of the air outlet 11 to form a side air outlet channel 5. It should be noted that at this time, the second air guide plate 3 is overlapped with the first air guide plate 2 to jointly block at least part of the air outlet 11 on the side of the first air guide plate 2 away from the gentle wind structure 4. The air outlet air volume is increased through the side air outlet channel 5, and it is beneficial to convey the low-speed air flow generated by the gentle wind structure 4 to a distance; and the main jet flowing out of the side air outlet channel 5 intersects with the gentle wind generated by the gentle wind structure 4, further improving the gentle wind effect.

[0035] Furthermore, the second air guide plate 3 is rotatably connected to the side wall of the air outlet 11 on the side of the first air guide plate 2 away from the gentle wind panel 41. In this way, when the first air guide plate 2 is opened to the first opening angle and the second air guide plate 3 is opened to the second opening angle, the main jet of the air outlet 11 flows out from the gentle wind structure 4 and the side air outlet channel 5 as much as possible, reducing air leakage.

[0036] In some embodiments, as Figure 3 shown, when the first air guide plate 2 and the second air guide plate 3 jointly close the air outlet 11, the second air guide plate 3 abuts against the closed area of the first air guide plate 2 and blocks the gentle wind area. It prevents dust and impurities from entering the main body 1 through the gentle wind structure 4, ensures the normal function of the main body 1 of the air conditioner, reduces the maintenance and cleaning frequency, and extends the service life.

[0037] In some embodiments, as Figure 3 shown, the first air guide plate 2 is provided with a lap groove 22, and the lap groove 22 is located on the side of the first air guide plate 2 away from the gentle wind area; when the first air guide plate 2 and the second air guide plate 3 jointly close the air outlet 11, the bottom of the lap groove 22 and one end of the second air guide plate 3 are lapped. The lap groove 22 is used to accommodate the second air guide plate 3 to block the gentle wind area. On the one hand, it reduces the height difference between the leeward side of the second air guide plate 3 and the peripheral surface of the lap groove 22, making the appearance surface of the indoor unit of the air conditioner more beautiful when the first air guide plate 2 and the second air guide plate 3 jointly close the air outlet 11. On the other hand, it can make the second air guide plate 3 and the gentle wind area provided on the first air guide plate 2 closely lap, so as to reliably block the gentle wind area and achieve a better sealing and dust-proof effect.

[0038] Furthermore, one end of the second air guide plate 3 is accommodated in the lap groove 22. When the first air guide plate 2 and the second air guide plate 3 jointly close the air outlet 11, the leeward side of the second air guide plate 3 smoothly transitions with the side of the first air guide plate 2 away from the gentle wind structure 4.

[0039] In some embodiments, as Figure 4As shown, when the first air deflector 2 is opened to the maximum opening angle and the second air deflector 3 is opened to the maximum opening angle, the first air deflector 2 and the gentle wind panel 41 are respectively arranged at intervals with the side wall of the air outlet 11 to form a side air outlet channel 5, and the second air deflector 3 and the first air deflector 2 are arranged at intervals to form a main air outlet channel 6, and the second air deflector 3 is located below the first air deflector 2. In this way, a part of the main jet flow of the air outlet 11 completes gentle wind through the air guide holes 21, the gentle wind structure 4 and the side air outlet channel 5; another part of the main jet flow blows out through the main air outlet channel 6 and converges with the low-speed and fluctuating air flow above it, and long-distance gentle wind supply can be realized.

[0040] In some embodiments, as Figure 5 shown, a plurality of air guide holes 21 are provided, and the gentle wind panel 41 is arranged opposite to the plurality of air guide holes 21. The air outlet air volume is increased through the plurality of air guide holes 21.

[0041] In some embodiments, as Figure 5 and Figure 6 shown, the diameter of the gentle wind holes 411 is smaller than the diameter of the air guide holes 21, and a plurality of gentle wind holes 411 are provided; at least two gentle wind holes 411 are arranged opposite to one air guide hole 21. In this way, when the second air deflector 3 is at the second opening angle and the first air deflector 2 is at the first opening angle, the second air deflector 3 can guide the air flow of the air outlet 11 to pass through the air guide holes 21 and the gentle wind holes 411 in sequence. The air guide holes 21 with larger diameters are used to ensure a larger air outlet volume, reduce the air speed and play a first gentle wind role. The plurality of gentle wind holes 411 with smaller diameters further disperse the air flow and reduce the flow rate, enhance the air mixing, and realize the second gentle wind role.

[0042] Furthermore, the gentle wind panel 41 and the first air deflector 2 are respectively arranged at intervals with the side wall of the air outlet 11 to form a side air outlet channel 5. On the basis of the first gentle wind and the second gentle wind, the main jet flow flowing out of the air outlet 11 flows out through the side air outlet channel 5 and converges with the low-speed air flow flowing out of the gentle wind holes 411 to form a third gentle wind; and it flows forward in a fluctuating manner after the convergence, with a natural wind feeling, and has a more comfortable body feeling compared with the mechanical wind with a constant flow rate generated by a conventional air conditioner.

[0043] In some embodiments, as Figure 5As shown, multiple soft wind holes 411 are arranged in multiple rows along the two side directions of the soft wind plate 41 and the diameter becomes smaller along the two side directions close to the soft wind plate 41. It should be noted that the two side directions of the soft wind plate 41 refer to the width direction of the soft wind plate 41; illustratively, the width direction of the soft wind plate 41 and the width direction of the first wind guide plate 2 can be set to be consistent or basically consistent, and then, the width direction of the soft wind plate 41 can be consistent or basically consistent with the width direction of the air outlet 11. According to the airflow distribution position, the diameter of the soft wind holes 411 away from the two sides of the soft wind plate 41 is made larger, so that more airflow passes through and the air volume is increased.

[0044] Furthermore, a plurality of air guide holes 21 are arranged at intervals along the two end directions of the soft air plate 41. It should be noted that the two end directions of the soft air plate 41 refer to the length direction of the soft air plate 41; illustratively, the length direction of the soft air plate 41 may be consistent or substantially consistent with the length direction of the air outlet 11.

[0045] Furthermore, each row includes a plurality of soft wind holes 411, and the apertures of the plurality of soft wind holes 411 in the same row are the same, and there is an angle between the central axes of the plurality of soft wind holes 411 and the first air guide plate 2. When the first air guide plate 2 is opened to the first opening angle and the second air guide plate 3 is opened to the second opening angle, the ends of the plurality of soft wind holes 411 away from the second air guide plate 3 extend toward the outside of the air conditioner indoor unit. In this way, it is possible to avoid as much as possible that other structures of the air conditioner indoor unit hinder the flow of soft wind generated by the soft wind structure 4; at the same time, since the airflow flowing out through the gap between the soft wind plate 41 and the first air guide plate 2 is less than the airflow flowing out through the soft wind holes 411, the airflow passing through the soft wind holes 411 will flow downward under the action of the low pressure located on its lower side, better avoiding obstacles, and facilitating the further forward flow of the soft wind.

[0046] In some embodiments, Figure 6 As shown, a plurality of mutually spaced connecting ribs 23 are provided on one side of the first air guide plate 2 facing the air outlet 11, and the soft air plate 41 is connected to the plurality of connecting ribs 23 to form a space with the first air guide plate 2. The plurality of connecting ribs 23 strengthen the supporting force of the soft air plate 41, which is conducive to ensuring the stability of the soft air plate 41.
